Yunyinggu (Viewtrix Technology)

Yunyinggu Technology (云英谷科技), which rebranded as Viewtrix Technology, is a Shenzhen-based fabless semiconductor company founded in 2012 that designs AMOLED display driver integrated circuits (DDIC) and color-rendering display solutions for smartphones and other devices. By 2024 sales volume it was the largest AMOLED display driver chip supplier in mainland China and the fifth-largest globally, with R&D and operations across Shenzhen, Shanghai, Beijing, and Hong Kong.
